Be itknown that I, .Tosnrn \VHITLEY, of Leeds, in .the county of York,h1gland, havc invented certai n new and useful Improvements in- Moldsfor (lasting (,lylindrical Forms in Metahof which the following is aspecification.

Thisinvcntion relates especially to the means States filed by meDecember 3, 1884, 0. 149,472; January 19, 1885, No. 153,299, and onthe-28th day of February, 1885, No. 157,406, and in Letterslatent ofGreat Britain granted to me in the year 157 9, No. 3,742.

The objects of the present invention are, mainly, to admit of thecasting being removed from the mold -immediately after thesolidification of the metal, and to admit of castings of different sizesand formsbeing produced in the same mold .by the use of differentlinings therein. With these ends in view 1 construct a combined moldconsisting of an outer cylinmay be rapidly revolved, and alining or moldproper which is removabletherefrom. The lining is usually cylindrical onthe interior and conical or slightly tapered-n the exteinternal form.-Thisconstruction permits the ready removal of the lining and casting,leaving the body or outer portion of the mold used without loss of time.I'propose to provide molds with spindles having interior screwsoperating loose end plates for the purpose of. forcing the castings outof the mold. The conical shells I perforate and rib for the escape ofgases. t

Inthe accompanying drawings, Figure 1 represents an elevation of myimproved appa- Fig. 2 represents an end elevation of the apparatus. Fig.3 is a vertical crosssect on through the middle of the n1o1d." Fig. 4 1sa/ longitudinal central section showing the an forced from the mold.

In the drawings, A re wesenls the cyliu- Serial Nth 216,:"56. (Nomodel.) l'alrnted in England Novemdrical body or outer portion of themold attached at one end-to a central supporting and driving shaft, 13,which ismounted in fixed supports orbearings, and provided withdrivshell 0 bolted thereto, and the end plate or ring,

H, boltedin place. Theouter or overhanging end of the body receivessupport from two wheels, d, upon which it bears, as shown.

The foregoing parts resemble in general construction and arrangementthose represented in my prior applications, and are not in those claimedas part of the present application. The body portion of the present moldd'rtfers from those heretofore i'nnse, intlntt it is made of conical ortapering form in the interior, its diameter increasing toward the headH.

G represents the lining or mold proper, the outer surface of whichismade of conical or tapering form and adapted to fit closely within theouter shell or body. This lining consists,

'eonnnonly, of ametal jacket, 1'), and the lining 0 of clay, sand, orother suitable refractory material, its inner surface correspondingprecisely with the external form of the castings to be produced.

Iprcfer to construct the metallic jacket of the lining with externalribs, j, as shown in the drawings, in order to produce air-spacesbetween the exterior of the jacket and the interior of the body. I alsoprefer to provide the jacket D and the outside body with perforations gto permit the circulation of air and the escape of the gases and vaporsdeveloped during the casting operation. The lining as a whole isinserted through the end of the body and screwed tightly in place bymeans of the end plate, 1!. To effect its removal afterthecompletion ofthe casting operation and after. the removal of the plate H, I employ atthe inner end of the body a plate, E, which may be operated in anysuitable manner, but whiehis preferably attached, as in Fig. 1, to ashaft or spindle in a central hole in the driving-shaft and acted uponat its outer end by a screw, d. By turning this screw the plate E iscaused to force the lining endwise. In consequence, of its taperedform'a slight end motion is snfiicient'to loosen the lining; so that itmay be readily gvithdrawn and replaced by another.

Having thus described my invention, what I 5 claim,is-

1. In a mold for casting metals, the combinationof the outer rotary bodyand thelinter nal lining or mold proper fre'movable endwise therefrom,substantial] y as'described and to shown. 1

2. In a mold for 'casting metals, the' 'c ombi nation of the removablelining having a tapered or conical exterior, andt-he external rotarybody having its interior surface adapted 15 to closely embrace thelining;

3. In combination with the external rotary body and the internal lining;the end'plate and screw'to effect the removal of the lining,.substantially as described.

4. In combination with the rotary external 20 body, the-internalremovable lining provided with. ribs and perforations, substantially asdescribed and shown.
